the official blog post on the dlc :
http://blog.us.playstation.com/2012/12/04/kat-and-emmett-in-ps-all-stars-details-and-new-level-revealed/
still gotta get my copy but i have exams though so i'll have to wait a little while
edit : seems as if kat can fly to a fair degree and emmett seems to have two stances one for long range and the other for short range
sounds very interesting
i also hope that they included emmetts jetpack for added mobility
